at Checker's beating Wendy's. But it's probably because of their chilli dogs tbh.

Sonic and Steak n Shake tho >>>>>

edit where I live shows White Castle....there's maybe like 10 in Chicago. lol

This isn't true. All of these type of charts are fake. There was an article about it somewhere but there's been an epidemic of these type of fake charts lately. I live in the light pink part of California and we do NOT step foot on Carl's Jr unless we have no other options.

The area where I'm from has pink on it. Either White Castle or Carl's Jr, whatever the color pink is.

Either way, there are no White Castle's or Carl Jr's in my area.The closest white castle is 18 miles away.
This is fake.

I only knew about two of those

How come McDonald's and Burger King are not really anywhere the biggest? Are they more global?

In n Out where I live! Not surprised.

In-N-Out where I live. They are like the only good fast food burger chain.

Only heard of Jack-in-the-Box, MacDonalds, Burger King, Wendys, and Dairy Queen. Mess.

This chart is invalid, the number one Burger Chain across the U.S is Mcdonalds by default.
